[gmx-users] [~SOLVED] Problem compiling Gromacs 5.1 with XL

[Jernej Zidar]

Hi Mark,
  I will send you the files.

  I managed to solve the issue by replacing the content of the
~/gromacs-5.1/src/gromacs/simd directory with files from Gromacs
5.0.6. Still curious about what could have caused such an issue.

Best,
Jernej
